Quantum Security Paradigms and Solutions
Post-Quantum Cryptography (PQC)
PQC algorithms are designed to resist both classical and quantum attacks while operating on conventional systems.
Key Families:
- Lattice-based: Kyber, Dilithium

- Multivariate Polynomial and Isogeny-based (experimental)
The U.S. NIST PQC initiative is currently finalizing standardized algorithms for global adoption.
Quantum Key Distribution (QKD)
QKD leverages the behavior of quantum particles (typically photons) to establish encryption keys that cannot be intercepted without detection.
Core Properties:
- Uses quantum states to encode key bits.
- Eavesdropping alters quantum states, triggering detection alerts.
- Enables real-time intrusion awareness during transmission.
Applications include secure communications, financial transaction systems, and national defense infrastructure.
